SHiNGLfZ-MACHINE.

SPECIFICATION forming part of Letters Patent No. 374.953, dated December 20, 1887.

Application filed November 20, 1886. Serial No. 219,466. (Modeh) T0 aZZ whom it may concern.-

Be it known that I, JONATHAN P. FERREN- BURG, a citizen of the United States, residing at Laforge, in the county of New Madrid and State of Missouri, have invented certain new and useful Improvements in Shingle-Machines;

and I do hereby declare that the following is a full, clear, and exact description ofthe same,

'reference being had to the annexed drawings,

making a part of this specification, and to the letters and figures of referencemarked thereon.

Figure 1 of the drawings is a side elevation of my improved shinglemachine, showing the supporting-frame partly broken away; Fig. 2, a longitudinal section taken on line a: a; of Fig. 6; Fig. 3, a transverse section'taken on line a z of same figure; Fig. 4, a detail end view, partly in section, showing theknives and means of adjustment; Fig. 5, a detail view of the reciprocating frame and plate, showing the manner of connecting the two together; and Fig. 6, a top plan View of a portion ofthe machine. e

The present invention refers to that class of shingle machines for which a patent was granted to me December 18, 1883, No. 290,222; and the object of the invention is to improve said machine in the several details of construction, substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents a suitable frame for supporting the operating parts of the machine, which may be of any preferred construction, and has upon its sides grooved guide-bars a, which form guides for a sliding frame, B, and plate D, hereinafter described. The frame B at its rear end is provided with upright arms I), which are rigidly attached thereto and disposed at a-suitable distance apart. In the space between the arms b works a crank pin or head, 0, and at each complete stroke of the pin it strikes block d, which forms a stop at each end of the arms. To this crank-pin c is loosely connected one end of a crank-arm, e, and the opposite end of said arm is suitably keyed to a transverse rotary shaft, as shown in dotted lines, Fig. 1, and the shaft is driven by the belt wheel or pulley G. The crank-arm c carries a crankpin block, 0, working between and guided by the arms I), connected at their ends by the stops d.

To the reciprocating frame B, at the front end thereof, are suitably-fastened slotted arms f, which extend beyond the end thereof, as shown in Figs. 2 and 5. To the slotted or projecting ends of the arms], above the frame B, a rectangular knife-edged plate, D, is connected by means of lugs g, projecting from the sides of the plate near its cutting or knife edge z, and entering the slots in the arms, and above the lugs and in the slots are placed rubber or othersuitable springs,h. By the manner above described of connecting the plate to the reciprocating frame and the employment of the springs a yielding motion is given to the plate, which is allowed to spring up in case of the shingle splitting thick at the opposite end from where knife-edge i of the plate has entered the block to cut therefrom the shingle.

The frame B at its front end is provided with plates j, which at the ends j are tapering in cross section, as shown in Fig. 2, to form wedge-like, holding devices to receive one end of the shingle. These plates are secured to the frame B by screws 7c, and immediately beneath the fastening-screwsand underneath the rear ends of the plates j "are placed rubber cushions k for the rear ends of the plates to rest upon, as shown in Fig. 2.

The platesj are not rigidly affixed to the frame B, but areloosely connected by the fastening-screws in such manner as to allow a slight yielding of the plates, the cushions causing the wedge-shaped ends of the plates to bear to their places to receive shingles, and if the shingle should run thick at the end from where the knife-edge t strikes it, or theblock that makes the shingles, the cushions would give and let the front edge of the plates spread apart to adapt themselves to the thickness of the end of the shingle when the extremity or outer end of the frame B strikes .it to crowd the shingle forward between the knives E F. The ends f of the plates thus form guides for the shingle.

A transverse stop, G, is suitably connected by pivoting it to the frame A at g", and the bolt B, (shown in dotted lines in Fig. 2,) from which the shingles are cut, is placed on the supporting plate D, and when the plate and frame are given a reciprocating motion back and forth by means of mechanism hereinbefore described, as the plate passes back it will be brought with its knife-edged in contact with the bolt and will rive off a shingle at each time it passes to the stop G. The block or bolt is prevented from following the plate D as it moves forward by the operator, who supports each bolt while it is being worked up into shingles.

The stop G is intended to keep the block or bolt from which the shingles are out from passing endwise when the knife-edge i strikes it. As the shingle is riven off of the bolt it passes underneath the plate Dand rests upon the table H,which is slightly concaved longitudinally from the center toward each end, as shown in Fig. 2, and is supported directly beneath said plate and reciprocating frame, and under the plate is a spring, I, which presses upon the shingle to hold it in proper position to pass between the knivesE F. At this point the frame B, in its forward movemenhstrikes the shingle and forces it between the knives E F, a shingle being thus cut at each revolution of the wheel or pulley G.

Dividing-bars J are provided upon each side of the frame A, said bars at their rear ends being connected to theforward end of the reciprocating frame 13 by bolts or screws Z, which pass through eyes a on the rear ends of the bars and through elongated slots at in the frame A, and are secured in any preferred manner to the frame B. As the frame B moves forward,the arms J are carried with it, and as these arms are of tapering form they will act as wedges to permit the knives E F to be gradually closed by the pressure of the springs o, as shown in Fig. 3, thereby giving the shingle the proper taper.

The ends of the upper knife, E, are connected to removable supports 19 by screws g, which loosely engage the blade and support it, while permitting it to have a limited rocking motion. Screws 1" are passed through the support in front of the screws q and bear with their points against the upper side of the knife. By turning screws r'up and screws q down the edge of the knife will be thrown downwardly, and by reversing the operation the edgewill be thrown upwardly. This adjustment of the knife is intended to give it the proper pitch to adapt it to different kinds of timber. The supportsp bear upon the upper edges of the dividing bars J, whereby said knife is acted upon by the movement of the bars and by the springs 0 above them.

The knife E is provided upon its upper side with spurs s, for the purpose of holding the shaving thereon, that is out from the shingle when the frame B makes its forward movement, and when the frame makes its backe ward movement the shaving will be retained on the knife by means of the spurs, so that it will notinterfere with the next shingle.

The ends of the lower knife, F, are fastened by one or more screws, 25, at each end thereof to brackets a, secured to the sides of the frame, and said brackets are vertically adjustable by set-screws 11. Such adjustment gives the knife the proper pitch to suit different kinds of timber, as in knife E. Screws a. pass through slots in the brackets u, to admit of the vertical adjustment of the bracket and hold it in its adjusted position by tightening the screws, and setscrews b are employed to adjust brackets c, which are mounted upon the brackets u, and upon which bear the lower edges of the bars J, screws d, like the screws a, holding the brackets in their adjusted position.

The adjustments of the brackets to c are for the purpose of raising or lowering the lower knife, F, and the lower bearing of the bars J, said adjustments being made to adapt the machine to shingles of different thicknesses.

The boxes 6' are held down upon the springs oiby means of the screwsf, to secure the tension of the springs and render them operative, and in such case would be independent of said screws, and the object of the springs would be to press down on the brackets 19 to keep them in position when released by the barsJ.

The spring I, hereinbefore described, is made in two parts connected together by a hinged joint, 9, and the rear end of the spring is securely attached to the under side of the knife-edged plate D. One section of the spring is provided with-lugs 71., which enter elongated slots i in thefree ends of arms K, the opposite ends of said arms being pivotally attached to the plate D. The arms K have shoulders Z, which strike on the block m as the plate D is forced forward, causing the arms at their rear ends to raise the spring I and prevent it from interfering with the knife E as the spring is carried forward by the plate D, and when said plate passes back the spring I is let down to its proper place.

The table H at its forward end is pivotally connected to the sides of the frame A in any "suitable manner, but preferably by means of a flat bar, 11*, secured to its under side, work ing in slots, and extended beyond the sides to form flat bearings 19, and at this end it is supported by a suitable spring, L, so as to have a vertical yielding movement when required, said spring bearing up against the under side of the table, so as to bring it to the proper height to cause the shingle to strike knives E It is evident that many Ways may be employed for pivotally connecting the table H to the frame A, and to regulate the angle to which it may be pressed upward by means of the spring L set-screws 0' are employed, which bear down against the flatshaped bearings 12, projecting from the sides of" the table and entering slots in the sides of the frame. By making the table H of the form shown I decrease the friction of the shingle on said table by decreasing the contact surface thereof.

A machine constructed in accordance with my invention is perfect in its operation as well as rapid in producing a finished shingle in a comparatively small space of time, and each.

of the various parts of the machine performs a valuable office in producing a uniform and perfectly shaped shingle.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
